Written shortly after the signing of the Oslo Accord in 1993, this essay expresses the ambivalent emotions of a Palestinian American who, despite her longing for peace, reconciliation, and an end to bloodshed, realizes with profound sadness that “Oslo” merely legitimizes the Israeli aggression. A true reconciliation, writes Majaj, must safeguard its claim to the future by working through and resolving the past, but the Oslo Accord ignores both the historical origin of the conflict and its all-too-real outcome.
The first complete translation into English of this Tibetan text, together with the informative commentary by the 8th century master Buddhaguhya. This text is of seminal importance for the history of Buddhist Tantra, especially as very little has been published concerning the origins of Tantra in India.
Timetabling problems are specific types of scheduling problems that deal with assigning certain events to the timeslots. This assigning is subject to certain hard constraints that should be achieved to get a feasible timetable and soft constraints that must meet as many as possible during forming a feasible schedule. This paper introduces an adaptive tabu search. Eleven benchmark datasets of the year 2002 are applied to show the effectiveness of the introduced algorithm. These datasets consist of 5-small, 5-medium, and 1-large (...) dataset. As compared to other methods from previous works, the proposed algorithm produces excellent timetables, in comparison with the algorithms as well as the current results, the mathematical results showed the high effectiveness of the suggested algorithm. It has a minor deficit on the medium or the small problem adaptive Tabu, and the tabu search relies on the tabu list and penalty cost when the change in the penalty cost is checked; if it is still unchanged for the period of iterations, the tabu list reduces automatically by ; furthermore, the tabu list remains constant.

The following article deals with the Mahā Kumbh Melā1 in Allahabad and the practices of Hindu world renouncers2 during this festival. In 2013, the year under study, approximately 120 million renouncers and lay pilgrims attended the festival. After a brief overview of the academic discussion on Hindu renunciation, the article proceeds to outline the mythology, history, and meaning of the Kumbh Melā. Subsequently, it presents the festival from the renouncers’ point of view. This section of the article summarizes the functions (...) of the festival, describes two particular forms of meals, and outlines the daily routine of the participants. Finally, the article discusses the inner-worldly asceticism of lay pilgrims, the main participants, as well as the ritual bathing during the festival, a crucial part of the Kumbh Melā for all participants.

The mathematical model of physical problems interprets physical phenomena closely. This research work is focused on numerical solution of a nonlinear mathematical model of fractional Maxwell nanofluid with the finite difference element method. Addition of nanoparticles in base fluids such as water, sodium alginate, kerosene oil, and engine oil is observed, and velocity profile and heat transfer energy profile of solutions are investigated. The finite difference method involving the discretization of time and distance parameters is applied for numerical results by (...) using the Caputo time fractional operator. These results are plotted against different physical parameters under the effects of magnetic field. These results depicts that a slight decrease occurs for velocity for a high value of Reynolds number, while a small value of Re provides more dominant effects on velocity and temperature profile. It is observed that fractional parameters α and β show inverse behavior against u y, t and θ y, t. An increase in volumetric fraction of nanoparticles in base fluids decreases the temperature profile of fractional Maxwell nanofluids. Using mathematical software of MAPLE, codes are developed and executed to obtain these results. (shrink)
Old military events pose a critical and severe problem for many countries, including the Egyptian northwestern coast. These result in extensive areas of surface/subsurface landmines that affect the economic development plans of many countries. Detection of these landmines becomes a target for many geophysical research teams. Currently, unconventional near-surface flight technologies, such as quad-hexacopters instead of regular land surveys, are used for safety reasons in the acquisition phase. We have introduced a new processing and modeling technique of magnetic data conducted (...) over mines or near-surface geophysical targets for accurate and precise determination of location and depth. The technique is based on the application of the Kaczmarz regularization method to the ill-posed magnetic inverse problem. The advantage of this method is the optimum transformation of regularized normal equations to an equivalent augmented regularized normal system of equations. The condition number of the updated system, which determines the degree of ill posedness, is greatly lower than the original one; this improves and guarantees a good solution to the system. The method is applied to an unexploded ordnance test site in the United Kingdom. Our results have determined that the technique is appropriate and promising in efficiently addressing a wide number of problems that are important to near-surface geophysicists, including UXO detection.

This study provides a scoping review of the recent conceptual developments about the deviant work behavior and counterproductive work behavior constructs. It also examines the specific types of deviant work behavior that have been more consistently investigated in the last decade, and whether they cover the interpersonal or organizational type of deviant behavior. In addition, individual, group, and organizational predictors of deviant work behaviors are examined. A scoping review of reviews was conducted on Scopus and Web of Science databases and (...) 54 studies published from 2010 to June 2021 were taken into account. Results show that more recent conceptualizations are based on well established models in the literature and consider the hierarchical structure of these two constructs. Recent reviews examine the relationships of deviant work behavior with job performance and ethical behavior constructs, the multilevel nature of deviant work behavior, and the consequences for the actor of the deviance. The specific types of deviant work behavior more frequently reviewed in the last decade are workplace abuse, incivility, ostracism, bullying and sexual harassment, and abusive and destructive leadership; this evidence suggests a much greater attention to interpersonal, rather than organizational, forms of deviant work behavior. Regarding antecedents, results show the continuing prevalence of personality factors antecedents. Limitations of the study and theoretical and practical implications for the field are also provided.

The explanation of the relationship between God and humans, as portrayed in Islam, is often influenced by the images of God and of human beings which theologians, philosophers and mystics have in mind. The early period of Islam disclose a diversity of interpretations of this relationship. Thinkers from the tenth and eleventh century had the privilege of disclosing different facets of the relationship between humans and the divine. God and Humans in Islamic Thought discusses the view of three different scholars (...) of the time: Abd al-Jabbar, Ibn Sina and Al-Ghazali. The relationships discussed in this work are: divine assistance, lu³f, according to 'Abd al-Jabbar; human love and attraction to the divine, 'ishq, according to Ibn Sina, and finally the mystical annihilation of the self in the divine unity, fana', of al-Ghazali. They introduce three approaches of looking at this relationship. In order to perceive these concepts, their perception of God and of the human nature will also be examined here. The starting-point of this research was the desire to set forth a variety of possible relationships which are all in accordance with Islamic belief, but nevertheless demonstrate diversity in understanding the relationship between the human and the divine which in turn suggests the concept of plurality within one religion. Examining these three concepts, which build firm connections between God and humans, reveals the importance of rational inquiry in medieval Islamic thought, not only because it was a source of logical arguments for Islam against its opponents but mainly because it built different bridges leading to God. God and Humans in Islamic Thought attempts to shed light on an important side of medieval rational thought in demonstrating its significance in forming the basis of an understanding of the nature of God, the nature of human beings and the construction of different bridges between them.

Das Verhältnis zwischen Vernunft und Offenbarung ist seit den Anfängen des Islams Thema muslimischer Gelehrsamkeit. Religiöse Wissenschaften, wie Hadith, Koranwissenschaften und Fiqh nahmen sich dieser Debatte frühzeitig an. Der vorliegende Sammelband zeigt die Wichtigkeit eines rationalen Umganges mit geoffenbarten Texten. Die Beiträge beschäftigen sich mit den Argumenten der Muʿtaziliten, Aschʿariten und Māturīditen und ihrem rationalen Ansatz der Koran- und Hadith Interpretation. Moderne Denker haben sich bei ihren Reformdiskussionen von deren nach wie vor gültigen Argumenten inspirieren lassen.
Der vorliegende Sammelband behandelt Aspekte der Rationalität in der Moderne, wobei gegenwärtige Positionen der islamisch-rationalistischen Theologie untersucht werden. Die Struktur des Buches ist der Tatsache geschuldet, dass die sogenannte moderne Periode islamisch- rationalistischer Theologie keine festen Denkschulen ausgebildet hat. Es äußern sich vielmehr jeweils einzelne intellektuelle Denker, die zwar miteinander kooperieren, indem sie gewisse Grundlinien gemeinsam verfolgen, jedoch hauptsächlich unabhängig voneinander forschen. Auch wenn es aufgrund dieser Gegebenheit schwierig erscheint, moderne Entwicklungen der islamischen Theologie zu klassifizieren, lassen sich die rationalen (...) Denkweisen der Moderne in drei Teilbereiche untergliedern: die neue Kalām-Wissenschaft, das philosophische Denken, und die Menschenrechte. Im ersten Teil behandeln die Beiträge jene Denker, denen es darum geht, den mittelalterlichen Kalām unter Zuhilfenahme moderner Theorien, wie der historisch kritischen Methode und neuerer hermeneutischer Systeme neu zu beleben. Die Beiträge im zweiten Teil behandeln muslimische Philosophen, deren Forschungen sich auf Bereiche jenseits religiöser Themen erstrecken, wie islamische Ethik, Demokratie und Säkularismus. Der dritte Teil des Bandes widmet sich jenen Denkern, die sich intensiv mit der Frage der Menschenrechte aus islamischem Blickwinkel befasst haben, wobei die Beiträge wiederum drei Themenbereiche behandeln: Rechte der Frauen, Toleranz und Interreligiöser Dialog.

Mobile app stores provide an extremely rich source of information on app descriptions, characteristics, and usage, and analyzing these data provides insights and a deeper understanding of the nature of apps. However, manual analysis of this vast amount of information on mobile apps is not a simple and straightforward task; it is costly in terms of human effort and time. Computational methods such as topic modeling can provide an efficient and satisfactory approach to mobile app information analysis. Topic modeling is (...) a type of statistical modeling technique for discovering abstract topics that occur in a set of documents. This study explores the relationship between features of Arabic apps and investigates how well the current predefined Google Play app categories represent the type and genre of Arabic mobile apps. Based on the textual app description analysis, we aim to design and develop a sustainable classification system using the Latent Dirichlet Allocation method of topic modeling in order to cover the Arabic apps classification in Google Play app store. Our study supports the hypothesis that the textual app descriptions are effective in suggesting new categories for Arabic mobile apps in Google Play app store. Also, the results indicated that the current classification on Google Play app store is not suitable for our case study “Arabic apps,” as well as it is not sustainable, as it can not cover the new app types including Arabic apps. This study offers an important contribution to Arabic app analysis and design, to improve app search and exploration in several domains such as business, marketing, and technical development. Furthermore, it provides insights for the future of Arabic app research and provides guidance for the development of an Arabic app dashboard that will support users on how to select an app based on their specific needs.

Fake news detection involves predicting the likelihood that a particular news article is intentionally deceptive. Arabic FND started to receive more attention in the last decade, and many detection approaches demonstrated some ability to detect fake news on multiple datasets. However, most existing approaches do not consider recent advances in natural language processing, i.e., the use of neural networks and transformers. This paper presents a comprehensive comparative study of neural network and transformer-based language models used for Arabic FND. We examine (...) the use of neural networks and transformer-based language models for Arabic FND and show their performance compared to each other. We also conduct an extensive analysis of the possible reasons for the difference in performance results obtained by different approaches. The results demonstrate that transformer-based models outperform the neural network-based solutions, which led to an increase in the F1 score from 0.83 to 0.95, and it boosted the accuracy by 16% compared to the best in neural network-based solutions. Finally, we highlight the main gaps in Arabic FND research and suggest future research directions. (shrink)
This work is an exposition of the philosophic conceptions basic to Mahayana Buddhism as found in the Maha-prajnaparamita-sastra a commentary on the Prajnaparamita-sutras and traditionally attributed to Nagarjuna. The sastra the earliest and most extensive work in this field is lost in its Sanskrit original and preserved only in a Chinese translation. Meaning of Sanskrit and Chinese terms are expounded concepts are made clear and supplementary materials are supplied in the notes. The study is prefixed with a short historical (...) account of the broad lines of Buddhist philosophy in its early stage. The aim of this work is to elucidate the meaning of the Middle Way, the way of comprehension. 'Everything stands in harmony with him who stands in harmony with Sunyata, which is not a rejection of existence or of understanding but of the misconstruction of the sense of the real or the error of misplaced absoluteness which is the origin of clinging and the root of conflict and suffering.'.

Very few researchers have reported on procedures of recruiting, obtaining informed consent, and compensating participants in health research in the Arabian Gulf Region. Empirical research can inform the debate about whether to adjust these procedures for culturally diverse settings. Our objective was to delineate procedures related to recruiting, obtaining informed consent, and compensating health research participants in the extremely high-density multicultural setting of Qatar.
This article first examines the textual structure of the Maudgaly?yana Sa?yukta of the Chinese Sa?yukt?gama in conjunction with its P?li parallel. Then it compares the main teachings contained in the two versions. It reveals similarities but also differences in both structure and content.
Web search engines usually keep users’ profiles for multiple purposes, such as result ranking and relevancy, market research, and targeted advertisements. However, user web search history may contain sensitive and private information about the user, such as health condition, personal interests, and affiliations that may infringe users’ privacy since a user’s identity may be exposed and misused by third parties. Numerous techniques are available to address privacy infringement, including Private Information Retrieval protocols that use peer nodes to preserve privacy. Previously, (...) we have proved that PIR protocols are vulnerable to the QuPiD Attack. In this research, we proposed NN-QuPiD Attack, an improved version of QuPiD Attack that uses an Artificial Neural Network based model to associate queries with their original users. The results show that the NN-QuPiD Attack gave 0.512 Recall with the Precision of 0.923, whereas simple QuPiD Attack gave 0.49 Recall with the Precision of 0.934 with the same data. (shrink)
This paper examines Sartre's dualistic ontology in the light of the non-duality asserted by Mahayana Buddhism. In the first section, I show, against the objection of Hazel E. Barnes, that Sartre and Buddhism have comparable theories of consciousness. The second section discusses Steven W. Laycock's use of Zen philosophy to solve the Sartrean metaphysical problem regarding the origin of being for-itself. This solution involves rejecting the ontological priority of being in-itself in favor of the Buddhist understanding of interdependent origination (pratitya-samutpada) (...) and emptiness (sunyata). Finally, I explain how this aspect of Buddhist thought is consistent with Sartre's ontology, thus making an acceptable solution. This consistency is possible if we understand Sartre's ontology as provisionally true in a sense gleaned from the Madhyamika and Yogacara schools of Indian Buddhism, which were influential to the formation of Zen philosophy.
